4 Claims. (Cl. 68-23) The present invention relates to washing machines, and more particularly to washing machines of lthe type in which a washing operation is accomplished by agitating the liquid and material contained therein and in which the tub is thereafter rotated to extract the liquid from the material to effect a partial drying thereof.

This application is a continuation-in-part of the parent application Serial No. 66,229 led December 20, 1948, now Patent No. 2,645,107, issued July 14, 1953, and assigned to the assignee of the present invention.

One object of the invention is to provide a washing machine which is relatively simple in construction with relatively few moving parts, and in which the rotating tub assembly is supported for operation by a single bearing, thus providing a device which is readily and easily maintained in operating condition at a relatively low cost.

Another object is to provide a simple, compact and efficient frame structure in combination with operating parts effectively supported thereby in a manner to meet the requirements for successful use and operation.

Other objects, features, capabilities and advantages are comprehended by the invention, as will later appear and as are inherently possessed thereby.

Referring to the drawings:

Figure l is a vertical cross-sectional view of an automatic washing machine embodying the present invention;

Figure 2 is a horizontal cross-sectional view taken substantially in the plane represented by lines 2 2 of Figure 1 of the drawings;

Figure 3 is an exploded view in perspective of the cabinet and base assembly for the washing machine shown in Figures l and 2 of the drawings; and

Figure 4 is a perspective View of the supporting base structure showing how the outer tub is mounted thereon.

Referring now more in detail to the drawings, an embodiment selected to illustrated the combined washing and drying machine for washing, rinsing and spin drying fabrics and the like, generally comprises an outer casing or cabinet 2 for completely enclosing the various parts of the washing machine, and which is supported upon a base structure 4 which also serves to support an outer stationary tub 6, an inner tub I rotatably mounted therein, and power operated means generally referred to as 8, for the washer.

The casing or cabinet 2 is formed of a plurality of parts made from sheet metal, one of said parts being fabricated from a single sheet of metal to provide oppositely disposed side wall panels I 2 and l5 and a back wall panel is, said panels being provided with an inturned horizontally flanged portion 20 along their upper edge, and the said panels l2 and it at the forward marginal edges remote from the back panel being provided with inturned oppositely disposed vertically extending flanges 22 and 24. These flanges 22 and 24 are adapted to mate withand be rigidly secure to similar vertical flanged portions provided on opposite sides of a curved front panel 26. This front panel is also provided-with an upper horizontally disposed inturned flange 28 disposed in the plane of the horizontal flanges 20 on the side and the back wall panels. The lower portion of the front panel terminates with an inwardly extending iianged portion 3@ above the lower edge of the side and back wall panels to provide a toe space for the operator. A separate cover or foot board 32 of somewhat the same contour as the front wall, but fitting closer to the forward marginal edges of the side Wall panels, covers this space to provide a smoothlooking front, the same being secured to the base assembly 4 through the inturned flanges 3% at the ends thereof. Disposed above the inturned horizontal flanged portions of the sides, back and front walls is a horizontal relatively flat cover or top 36, preferably formed from a single piece of metal and having vertically extending side portions 38 terminating in the inturned horizontal anged portions All at the lower end thereof which mate with the flanged portions I8 and 28, the same being fastened thereto in any desired manner to form a substantially rectangular unitary box structure with an open bottom adapted to t about the base assembly Il.

The front panel 2li is provided with an opening 2'! preferably at the upper portion thereof, in which is mounted a nameplate 29 of translucent material and made easily readable by means of a pilot light 3|.

The top wall or cover 33 is formed with a centrally located access opening defined by a downwardly and inwardly extending flange it to permit access to the inner receptacle or tub lil. This opening is normally closed by the lid or door d2 hinged by the U-shaped member it at one end thereof by means of horizontally disposed hinge pins 46 mounted in spaced brackets 4S on the under side of the cover or top wall 3S. This lid swings upwardly to a substantially vertical position and is provided with a handle or grip 5l) at the end opposite the hinge $4 to provide means for raising or lowering the lid. Adjacent the front panel 26, the top cover member 36 is formed with openings 52 and 54 through each of which loosely extends a shaft of a control device as described in the parent application.

It will be noted that the lower edge portion of the back and side walls is provided with a series of openings 88 adapted to be aligned with similar openings in the base structure Il for receiving screws, bolts or other means, for rigidly securing the outer casing to the base member :S to provide a unitary structure. The back wall of the cabinet may also be provided with a plurality of spaced louvers 90 to permit circulation of cooling air around the motor. The back panel of the cabinet is also provided with an opening 92 through which water supply and removal conduits extend.

The base structure comprises four horizontally disposed L-shaped angle irons 94, gli, S8 and |30. disposed to form a rectangular assembly, one leg of the angle irons forming the outer vertical walls of the assembly and the other leg thereof being disposed inwardly to form the horizontal bottom wall of the structure. The horizontally disposed leg portions of the angle irons are overlapped and are fastened together in any desired manner, as by spot welding, or the like, to form a rigid structure. The vertically disposed leg portions of the angle irons constitute structure to which the cabinet 2 is attached or connected as hereinbefore described. Extending between the oppositely disposed angle irons 95 and MJS, and rigidly secured in any desired manner to the horizontally disposed leg portions thereof, is an arched U- shaped channel member |92 formed with a centrally disposed opening IM adapted to receive a combined radial and thrust bearing, generally referred to as |06, which constitutes the sole means for supporting the inner receptacle it on the base structure 4. At each corner of the base assembly 4 there is provided relatively short vertically upstanding L-shaped angle irons |08, HG, ||2 and ||4 which are rigidly secured to the vertical leg portions of the angle irons 34, S5, 98 and |88 and each of which is provided with an inwardly disposed bracket element H5 secured to the upper end thereof. Foot elements ||1 secured to the outer tub 6 are also secured to the bracket elements I i5 for forming supporting connections for the outer tub 6.

Adjacent each corner of the base assembly e there is provided an adjustable leg i i t which may be adjusted to maintain all four supporting points of the assembly in contact with the iioor or support for the washing machine to maintain the same level and to provide for a solid contact between the machine and the floor or support to reduce vibrations which tend to be set up in the cabinet during operation of the machine.

The outer stationary tub or receptacle 5 is preierably formed at its lower portion with a cylindrical wall |20 and its upper portion has a frustoconical wall |22 terminating in an open upper end adjacent the cover or top wall 3S to permit access thereto. The upper open end of the tub is provided with an inwardly extending flange |24 formed with a semi-spherical groove in the upper portion thereof which is adapted to receive an annular hollow ring shaped seal |25 adapted to engage and press against the under face of the cover or top wall 36 to maintain a fluid-tight seal between the outer receptacle and the cover and to prevent water from being forced from the 4 outer receptacle into the outer casing or cabinet 2. The bottom |21 of the outer stationary tub is formed to facilitate the drainage of washing iiuid therefrom to a conically shaped passage |28.

The bottom |21 of the stationary tub E is formed with a centrally disposed opening defined by the upstanding annular flange |54 to which is secured stand-pipe |56 in the form of an upstanding sleeve or tubular shaped member. The sleeve |56 projects downwardly below the bottom of the tub, as at |58, and extends upwardly above said bottom and terminates in an enlarged cylindrical portion |63. This up-standing sleeve provides means through which concentrically arranged shafts |62 and |64 extend, these shafts being driven to actuate the agitators 56 and |68 and for rotating the inner tub or receptacle i0. The up-standing sleeve |58 is spaced from the concentrically arranged shafts to permit lateral and gyratory movement thereof, andr the saine is of sufficient height to prevent any washing liquid which accumulates in the bottom of the tub G from owing out of the central opening defined by the flange |54. The central portion of the tank bottom |21 adjacent to and outwardly of the annular ange |54 is provided with a spherical surface |18 for a purpose to be hereinafter more fully disclosed.

The inner rotary tub o1' receptacle ID is disposed within the upper portion of the stationary tub 6 and is spaced from the side walls thereof a sufficient distance to permit of a certain amount of lateral or gyratory movement thereof without contacting the same. The said inner tub is in the general form of a truncated spherical hollow body member terminating in a horizontal plane at its upper marginal edge to provide an access opening |12 which is in alignment with the opening in the cabinet formed by the iiange 4i! whereby the interior thereof is accessible to the operator. This hollow body member is provided with a substantially horizontally disposed bottom wall |14 opposite the opening |12.

The upper and lower portions of the receptacle iB are formed with mating hub portions which extend outwardly and in opposed relation to one another to provide the horizontally aligned hubs |16 and |18 which are adapted to receive the stub shafts |86 and |82 secured therein by means of pins or the like |84, upon which the agtators l 65 and |68, respectively, are mounted for rotation about a horizontal axis. The tub I0 is further provided with the oppositely disposed offset portions 2|if| and 266 to accommodate the agitators ISG and |38, respectively, and the driving mechanism therefor, and in the side wall of which is formed a plurality of relatively large openings ist, each having its lower marginal edge disposed slightly above the horizontal axes of the stub shafts |39 and |82 which define a maximum liquid level for liquid within the tub l and serve to permit the washing liquid to flow therethrough when the level thereof tends to rise above the plane of the lower marginal edges of these openings and also when the tub is rotated about its vertical axis.

The bottom wall |14 of the tub li) is provided with an integrally formed housing structure |88 concentrically arranged with respect to the vertical axis of the receptacle I0 and having an annular and outwardly extending ange |90 seating upon, and being secured as by bolts or the like, to the outwardly disposed flange |92 of the hub member |94 which is secured to the outer'hollow shaft 64 through the medium of pins ISS, or any other suitable connecting means. The hollow rotatable shaft itt extends downwardly through the opening provided in the sleeve member |56 of the outer tub E and is formed at its lower end with a reduced portion |98, having a shoulder 200 engaging a combined radial and thrust bearing assembly |26, whereby the inner tub is supported axially solely by this bearing, the said combined radial and thrust bearing assembly serving as a pivot point about which the said tub I0 is rotated, as will be explained more fully hereinafter. The bottom of the tub lil adjacent the central axis of the same, and immediately above housing |88, is provided with a raised or crowned surface 202 for accommodating certain driving mechanism dis posed within the said housing |83.

The agitators |65 and |68 are of similar construction and each comprises a substantially spherical shaped base or disk portion 228 fitting within the offset portions 28d and 23S, respectively, to provide a substantially uninterrupted inner surface for tub it. The agitators are removably secured to shafts |86 and |82 by means of the spring retaining rings 2 0 fitting within complementary annular grooves formed in the shafts |30 and |82 and the hubs 2|2 and 2|4 of the agitators |66 and |53, respectively. The disk portions 208 of the agitators are provided with a plurality of openings 2 IE which extend therethrough so that water or washing liquid may ow through such openings to the openings Hit and into the outer tub 6. Each of the agitators is preferably provided with a single vane, as illustrated, which extends vertically outwardly from the base and extends substantially across the entire width of said base. These vanes, when the agitators are mounted within the receptacle It, project toward the center of the inner tub lll and the same are capable of agitating the liquid disposed within the tub or container when the same are rotated.

The inner shaft |62 is journaled in the outer sleeve |66. with its upper and lower portions in the bearings 2HE and 220, respectively, and extends upwardly beyond the flange |82 and into the housing ESS, the upper end thereof having the bevel pinion 222 secured thereto. The bevel gear 222 is mounted on the upper surface of the outer shaft itil through the thrust bearing 224, which prevents the inner shaft |62 from moving in a downward vertical direction, and to position the same with respect to the hollow shaft |64. The bevel pinion 222 meshes with the bevel gears 225 and 228 mounted adjacent the inner ends of drive shafts 236 and 232, respectively, which extend outwardly and horizontally in opposed relation and are journaled adjacent their inner endg in the inner bearings 23d and 2te formed in the housing |88 and adjacent their outer ends in the bearings 238 and 24m. The bearings 233 and 240 are provided in the recess housings 262 and 2M disposed adjacent to and immediately below the agitators |86 and E53, respectively. Mounted on the drive shafts 25s and 232 adjacent their outer ends are spur pinions 2de and 228 which mesh with spur gears 25u and 252 of relatively large diameter, which may be integrally formed with the agitators |56 and liti), respectively, or formed separately and connected thereto. lt will be seen from the draw` ings, that as the drive shaft le? is rotated in any given direction that the bevel gear 222 connected `thereto will rotate the bevel gears 226 and 228 in opposite directions for driving the shafts 236 and y232 and the agitators 62 and 552 operatively connected in driving relation thereto, in opposite directions. Due to the opposite rotation of the agitators, the liquid or cleaning fluid within the receptacle I0 is forced from one side or face of one of the agitators to the oppositely facing side of the other agitator and is forced downwardly and over to the other side of the face thereon and is discharged therefrom and is then caused to flow back to the adjacent face of the first agitator by the second agitator. The opposite rotation of the agitators causes the liquid to flow in a continuous direction in a horizontally circular manner between the agitators and in a vertical semicircular manner at and adjacent the agitators. The iiow, however, will be very turbulent as the body of liquid is moved in the general direction indicated.

The housings 242 and 244 formed as an integral part of the tub or container I0 adjacent the junction of the side and bottom walls are each in communication with the interior of the tub by way of channels, such as 254, and the openings 2 I6 in the agitators. Laterally and on both sides of shafts 230 and 232, the housings 242 and 244, respectively, are formed with radially extending portions 266 connected to the bottom wall |14 of the inner tub to provide passageways communieating at one end with the recesses formed by the housings 242 and 244 and at the other end with the interior of the inner tub I0 through openings 268 provided in the bottom wall |14.

Each of the housings 242 and 244 is provided with an opening exteriorly of the tub I0 which is closed by a wall element '256 connected to the tub I0 in any desired manner. The wall is apertured, as at 258, to permit water or cleaning fluid to be discharged from the tub IE) when the same is rapidly rotated in the washing cycle. The opening 258 is normally closed by a valve member 250, spring pressed into such position by means of the spring member 262 which permits the valve member 26|) to be opened against the action of the spring during relatively high speed of the tub I0. The outward movement of the valve members 260 is limited by stop elements 264 connected to the tub I0 in any desired manner.

The primary object of the valves 26|! is to provide means for flushing dirt and other foreign matter away from the pinions and gears, which may have collected during the washing cycle in the recesses formed by the housings 242 and 244. Water or cleaning fluid for this ushing operation passes from the interior of the tub le outwardly through openings 2 ||i in the agitators and channels 254 and through the openings 268 into the recesses formed by the housings 222 and 244.

As previously pointed out, the hollow shaft |54 is formed with a reduced portion |98 providing the shoulder 2130 which is in operative association with the radial and thrust .bearing assembly generally referred to by the reference numeral |05. More particularly, the said shoulder 209 engages the inner race ring 216 of the bearing IMS to support the shaft |64 in vertical position. The outer race ring 212 is mounted in and connected to an annular member 214, S-shaped in vertical crosssection, the same being provided with a lower inturned flange 21E for supporting the outer race ring 212 and with an upper outwardly disposed flange 213 which overlaps and engages an annular shaped rubber bushing 285. This bushing, which may be of any desired resilient material, is positioned by an annular dish-shaped retaining member 282 and has an inwardly disposed flange 224 on which the annular resilient bushing 280 is mounted and an upper and outwardly extendaovefrre ing ange 286 disposed within the openingV |04 of the channel member |02 and overlaps the same and is rigidly connected thereto in any desired manner.

The extreme lower end of the shaft |62 projects downwardly beyond the restricted portion |98 of the hollow shaft |64 and has a driving pulley or wheel 288 keyed thereto in any suitable manner, whereby the same is adapted to drive the shaft |62. It is to be noted that the reduced end portion |98 is disposed to have its end in abutting relation to the hub of the pulley 1288 so as to prevent relative axial movement of the two shafts |62 and |64.

From the foregoing it will be seen that the combined radial and thrust bearing |06 not only supports the receptacle I but, through the thrust bearing 224 disposed between the bevel pinion 222 and the supporting hub mmber |94, maintains the pulley 288 in its proper operative position. As the receptacle |0 is caused to move laterally within the stationary tub 6 during the spinning operation, or if the same is moved in any manner away from its vertical position, the receptacle I0 will tilt about the bearing assembly |06, it being noted that the bearings constitute the sole support for the receptacle l0 and the agitators, and their operating mechanism. The pulley 288 is dish shaped in such a manner that the horizontal plane defining the center of the groove for the driving belt 290 fitting therein, extends through the pivot point of the bearing assembly |06 in order to minimize deflection of the driving belt.

In order to maintain the receptacle I0 in substantially its vertical position, there is provided a combined stabilizing and damper mechanism, generally referred to as 292, disposed immediately below the bottom |21 of the stationary tub 6. This mechanism includes a hollow sleeve-like member 294 surrounding the hollow shaft |64 which is provided with two radial bearings 296 and 2% journaled upon the hollow shaft |64 adjacent the upper and lower end portions of the tubular member 294. The upper end of the central tubular member 294 is formed with a spherical shaped wall 300 reinforced by a plurality of downwardly extending webs or brackets 302 which provides a spherical shaped friction surface. The spherical shaped wall 300 is adapted to contact a spherical shaped member 304 formed of friction material mounted upon the lower wall |27 adjacent the spherical shaped portion |10 through an annular tubular member 308 which surrounds the downwardly extending end portion 58 of the sleeve |58. The hollow tubular member is preferably formed of some resilient material, the same being adapted to engage an annular shoulder 308 provided adjacent the inner marginal. edge of the member 304. Adjacent the lower end of each of the webs or brackets 302, four being provided in the illustrative embodiment, there is provided an opening engaged by one end of a coil spring 3|0, which has its other end connected to the stationary tub 6 by means of a bracket 3|2 connected to the bottom wall |27 thereof. rEhese springs are uniformly spaced around the member 294 so that springs of each pair are disposed in opposite relation to one another and due to the angular position of these springs with respect to the tub and the connection. at the lower end of the webs 302, a component of the spring force is applied in a vertical direction to the friction member 304-. Since each spring is equally loaded and opposed by an oppositely disposed spring, the tub l0 will be maintained in its vertical position under normal conditions. Should the receptacle I0 tend to move away from the vertical, the spring forces acting through the member 294 will tend to return it to its neutral or vertical position where the spring forces are all equal and opposite. As will be apparent, the surface of the spherical wall 300 is forced by the springs 3|0 toward the friction member 304 and, as the tub tends to move in a horizontal plane, a certain portion of th energy tending to move the tub is absorbed by the friction member. This friction member, therefore, tends to reduce the amplitude or extent of horizontal movement of the tub and absorbs some of the energy applied thereto.

The driving means for the pulley 288 comprises a reversible motor 320 vertically mounted in, and supported by a frame 322 pivoted to the stationary bracket; 326 connected to the vertical supporting element IES of the base structure 4 for movement about a vertical shaft or axis 324 in remote relation to the axis of the motor. A drive pulley 328 having a V-shaped peripheral groove is connected to the rotor shaft of the motor and is adapted to drive the pulley 288 through the belt 290. The belt 290 is maintained under its proper belt tension by means of a horizontally disposed preloaded spring 330 connected at one end to the housing 322 and at its other end to the bracket 332 secured to the base assembly 4, said spring acting to move the motor and its supporting frame 322 about its vertical supporting axis 324 in a direction away from the driven pulley 288.

In bringing the tub l0 and its contents up to spinning speeds, a motor of the size which it is desirable to use in a washing machine of the type herein disclosed, will not attain its operating speed fast enough to prevent the starting winding thereof from burning out. In order to eliminate this difficulty, the motor 320 is pivotally mounted as described and operates in a counterclockwise direction, as disclosed in Figure 2 of the drawings, to spin the tub I0 and in a clockwise direction to rotate the agitators |66 and |68.

The pivot 324 is arranged with respect to the motor so that the reactive torque of the motor operates against the spring 33) which holds the belt 2.9i) tight so that the belt is loosened during the rotation of the motor in a counterclockwise direction sufficiently to allow the motor pulley 328 to slip on the belt 292. The spring 330 is adjusted so that the motor pulley will slip on the drive belt at a value considered to be the maximum safe output torque of the motor. In the operation of the washing machine, as soon as the motor is rotated in a counter-clockwise direction, as viewed in Figure 2 of the drawings, the same immediately comes up to speed and slips on the belt 290 and provides a maximum safe torque which gradually accelerates the pulley 268 and the structure which is to be rapidly rotated thereby, including the tub I0 and the contents thereof. When the motor is rotated in the reverse direction for operating the agitators, it is evident that the torque required to cause slipping is much greater as the pulley tends to move up on the side of the belt which is closer to the pivot point 324 and, accordingly, there is less leverage tending to move the frame structure 322 against the action of spring 330. With this arrangement, slipping of the motor can be provided for spinning the tub i6 in one direction and ample torque is provided for operating the agitators without danger of belt slippage in the reverse direction. When theV motor 32|) is operated to spin the tub l0 there will be a tendency under some conditions for the motor to hunt or oscillate about the pivot point 324. In order to prevent this oscillation or hunting of the motor a friction damper is provided. This friction damper comprises a leaf spring 384 connected to the motor housing at one end thereof and being provided at its other end with a transverse groove adapted to hold the friction member 336 therein and against the inside face of the angle iron lle upon which the motor is pivotally supported.

Rigidly secured to brackets 332 and 3323 of the base assembly, and disposed between the drive and driven pulleys 328 and 288, is a reversible pump 3l|lill capable of operating in either direction of rotation of the motor 32|) for pumping liquid from the tub 6 either through a con duit 342 to drain, or through a conduit 344 back to thereceptacle It for recirculation. The pump 340 is driven by the motor 32e through motor pulley, belt 356 and pump pulley 352.

Mounted on the inner side of the hub of the driving pulley 288 is a one-way clutch 38! comprising a body portion having tapered slots therein which have their openings disposed adjacent the reduced end portion |88 of the hollow shaft |64. A plurality of rollers are disposed in these slots so that when the driving pulley 288 is rotated in a clockwise direction, as viewed in Figure 2 of the drawings, as, for example, when the agitators |66 and |88 are being oper-ated, the roller will be disposed in the larger part of the slots and, accordingly, nc turning movement is applied to the hollow shaft li/i upon rotation of the pulley 288. At this time the pulley 288 which is connected to the shaft 52 causes rotation thereof for operating the said agitators. When the direction of rotation of the pulley 288 is reversed, however, the rollers move along the tapered slots and grip the hollow shaft I to effect a driving connection between the pulley 288 and said hollow shaft |64. It will be apparent that during this operation the inner and outer shafts |62 and |84 are rotated together in the same direction, and ai; the same speed, and inasmuch as there is no relative movement therebetween, the agitators iii and |68 are maintained stationary with respect to their axes of rotation but the same will be rcvolved about the vertical axis of the tub Iii.

During the rotation of the inner shaft ISZ, when the agitators |66 and |58 are rotated for a washing operation, there is a natural tendency for the receptacle i0 to rotate with the inner shaft |62 which, if permitted, would reduce the eiectiveness of the washing action of the agitators. In order to maintain the tub I8 stationary during the washing operation there is provided a one-way clutch 386 mounted in the lower end of member 294 of the stabilizing and damper mechanism 292 which is adapted to hold the tub I8 and to prevent its rotation. This one-way clutch is similar to the one-way clutch 384, except that the tapered slots formed in the body portion are disposed oppositely to the tapered slots in the one-way clutch 381i. When the shaft |82 is rotated to rotate the agitators, the rollers of this one-way clutch 386 are positioned to grip the hollow shaft |64 and, inasmuch as the stabilizing and damper mechanism 292 is connected to the stationary tub 8 through the springs 3|0, rotation of the hollow shaft |851 cannot occur, When the rotation of the driving l0 pulley is in the reverse direction and the one- Way clutch 384 grips the outer hollow shaft |64 to cause the tub i9 to rotate about its vertical axis, the one-way clutch 388 is released.

By means of the cooperative action between the various supporting elements themselves and between said supporting elements and the various operating elements herein described a combination is provided for producing a simple, sturdy, reliable and emcient washing machine adapted to meet all of the requirements for successful operation.
